Lime was the primary ingredient in most stains in the old days -- it was called a 'lime wash'. It can be used to stain all porous materials including masonry, concrete, and stucco without causing any of the moisture problems that modern finishes may cause.

Concrete will allow water or water vapour to move through it quite easily, so any wood in contact with concrete must either be pressure treated wood, or you should have a plastic separator between the wood and the concrete. A simple slip of polyethylene plastic is all it takes to prevent rot at t...
Concrete, outdoors in the Canadian climate, has a particularly difficult time surviving. Walkways, patios, driveways and the like must have as much as 4 to 6 inches of gravel as a drainage base to minimize the effects of shifting from frost movement in the soil. Drainage around these areas has to...
Air Entrainment
When ordinary concrete gets wet and then freezes, the ice crystals can cause surface chipping, or even more serious fracturing. All outdoor concrete in Canada, even by code, should be what we call air entrained. This means that there are microscopic air bubbles in the concrete ...
The world of tiles is changing rapidly.
Twenty years ago we generally had a range of tile sizes from 1 ft x 1 ft down to tiny mosaic tiles. This made tiling relatively simple because slight changes in the flatness of the surface could be adjusted for at the next grout line. In fact that is...
The old days of stacking structure
In the old days, before we had specialized hardware like joist hangers, we would always create beams, or low lying ledger boards and place the joists on top of them with some kind of toe-nail attachment.
The arrival of joist hangers
When joist hangers came in...

Not only the paint was peeling off, but the block itself was breaking off.
This is a sign o...

Lokesh from Newmaket has a problem with his concrete driveway not being level. It actually flows water into the house. If you don't want to dig it all up and start over (which sometimes is the cheapest solution), you can actually raise the concrete slab to level it or even slope it away from the ...
